This is the user manual of Extech CG204 coating thickness tester, which can measure the thickness of coating on non-ferrous metal and ferrous metal by magnetic induction and eddy current methods respectively.
The Extech CG204 is a portable meter designed for non-invasive coating thickness measurements on ferrous and non-ferrous metal substrates. It utilizes two measurement methods: magnetic induction for ferrous metals and eddy current for non-ferrous metals. The device features an intuitive push-button programming menu, a backlit LCD display, and includes five film reference samples and two metal substrates for calibration.
The meter uses magnetic induction for ferrous metal substrates and eddy current for non-ferrous metal substrates.
The meter will automatically turn off after approximately 3 minutes to conserve battery life.
The statistical analysis utility can evaluate up to 80 readings.
